}
    用户登陆管理系统：
        1. 注册新用户
            username
            password
            gender
            email
            age

        2. 用户登陆
            username
            password
        3. 注销用户
            username
            password
        4. 显示用户信息
        5. 退出系统




	1. 用户名和密码分别保存在列表中;
	2. 用户登录时，判断该用户是否注册;
	2. 用户登录时，为防止黑客暴力破解, 仅有三次机会;
	3. 如果登录成功，显示登录成功(exit(), break).
